Note

This version improves SolidityNode block synchronization performance by turning off the index, but the interfaces getTransactionById, getTransactionsFromThis and getTransactionsToThis will not be available, since these three interfaces depend on the index. If the SolidityNode sync block is slow, you can use this version, it will greatly speed up block synchronization. Otherwise, there is no need to upgrade this version.

Improve

Add switch option for transaction index in solidityNode.

Turning off the index will significantly improve the performance of the SolidityNode sync block

If the index is turned off, the interfaces getTransactionById, getTransactionsFromThis and getTransactionsToThis will not be available.

A new feature for SolidityNode. If you don't use an index, that is, without using the interfaces getTransactionById, getTransactionsFromThis and getTransactionsToThis, you can copy the FullNode database to the SolidityNode to sync block.

The interface totalTransaction is deprecated, because this interface takes a very long time.

Using

Need to manually modify the configuration file to turn off the index.

To turn off index, add index.switch = "off" under index.directory in the configuration file(default value is "on", refer to the relevant configuration of this configuration file).

The entire VM system uses bandwidth and energy to represent aggregate system resources. The underlying concept of memory, cpu, etc. is shielded, improving accessibility of the system and reducing the learning cost for DApp development.

Release v2.0.8 adds optimizations to the querying system, and does not need to delete the database compared to 2.0.7.
We recommend everyone update to the latest release, but it is not mandatory for Super Representatives.

Note

Solidity Node using this version need to delete the database compared to Odyssey-v2.0.8. This is the only difference between the two versions. If you don't want to delete the database, you can use Odyssey-v2.0.8 please.

Release v2.0.7 adds optimizations to the querying system.
We recommend everyone update to the latest release, but it is not mandatory for Super Representatives.
